Your mod is very useful, but the one limitation I can find is the rare case that a block only accepts fluid from the bottom. One example is Astral Sorcery's Containment Chalice. I'm trying to avoid lots of "high tech" mods that don't have at least a vanilla or partial magical feel to them which leaves me with few options of piping items and fluids. Your mod fits the bill fairly well except that I can't use it for the one thing I really want a fluid pipe to do.
